A still further object of the invention is to provide a generator of this class including a minimum number of partshaving exceedingly simple structures, one which is capable of being easily assembled or disassembled, one which is thoroughly eflicient and reliable in operation and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will be better understood as the description proceeds, the invention resides in certain novel features of construction, and in the combinatlon and arrangement of parts as will be hereinaftermor fully described and claimed. 7

The figure is an elevation of the generator apparatus embodying the features of my invention.

Referring'to the drawing in detail it will be seen that 5 designates a solid reagent container wherein will be disposed different materials such as zinc for instance. This receptacle is in the form of a bottle having the open neck 6 at its upper end. The bottle is. aperture ch k adjacent its bottonn-ato i. receive may be cor portion ofthereceptacle 5s zrh liquidiconr ta111en91s also 111! the form of zabohtle ll-RV? ing at its upper end a neck 10, at itsniuitermesh ateportion a' neck; 1:1, and at': rtszbotttom portion: a -ncckv'18. fllhewcontaanerr 9;:isareri the same level with the container- 53uhlrose or the like :14, is -disposeds between; the ttvo necks 8: and 11': in -order that a! tube 155 mm;-

The construction of the tube 17 tion with the container 9 and receptacle 5 respectively through'branches 18 and 19 rewith its branches 18 and 19 in communica--' ator Will now be clearly understood by those skilled in this art without a more detailed description thereof. It is desired, however, to point out that the present embodiment of the invention has been disclosed merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It Will be apparent that numerous changes in the-details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what I claim as new and desire to secure by Letters'Patent is 1. A gas generator comprising a liquid container, a reagent receptacle on the same level with the liquid container, a liquid supply container at a higher level than the liquid container, means communicating the bottom of the liquid supply container with the bottom of the liquid container, means communicating the tops of the liquid con tainer and the reagent receptacle, a take bottom of the liquid supply container withoff tube incorporated in said means, and means communicating intermediate portions of the liquid container and the reagent receptacle. 1

2A gas generator comprising a liquid container, a. reagent receptacle on the same level with the liquid container, a liquid supply container at a higher level than the liquid container, means communicating the vture.

the bottom of the liquid container, means communicating the tops of the liquid container and the reagent receptacle, a take off tube incorporated in said means, means communicating intermediate portions of the liquid container and the reagent receptacle, said last mentioned means having an upwardly disposed apertured tubular portion within the liquid container.

3. A gas generator comprising a liquid container, a reagent receptacle on the same level with the liquid container, a liquid supply container at a higher level than the liquid container, means communicating the bottom of the liquid supply container with the bottom of the liquid container, means communicating the tops of the liquid container and the reagent receptacle, a take off tube incorporated in said means, means communicating intermediate portions of the liquid container and the reagent receptacle, and draining means associated with the bottom portion of the reagent receptacle. I

4. A generator of the classdescribed comprising a reagent receptacle, a liquid container, a liquid supply tank, said container and receptacle being on approximately the same level and said tank being on a higher level, means communicating the bottom of the tank with the bottom of the container,

means communicating the intermediate poi tions of the receptacle and container, and a take ofl tube having branches engaged one with the top of the receptacle and the other with the top of'the contain-er.

In testimony whereof I aflix my signani'vienr I WARRIOK'.
